Lady Gaga, a singer who is famed for her flamboyant style, has recently become more open about her relationship with Vampire Diaries actor Taylor Kinney.

The couple, who met while filming Gaga’s music video “You & I,” has become decidedly closer since the shoot. However, some are disappointed that the relationship developed while Kinney was still in a relationship with Brittany Sackett, a 26-year-old real estate agent from San Diego.

Sackett discovered that Kinney was cheating on her when she received an accidental call while the actor was on a date with Gaga, and could hear Gaga speaking romantically to him in the background.

Infidelity with celebrity couples is a frequent issue. Infidelity expert Ruth Houston, author of “Is He Cheating On You?” gives many reasons why celebrities are more prone to cheat, which include: peer pressure, ego, entitlement, impunity, and even revenge.

Some fear the impact that celebrity infidelity may have on relationships.

“I have taken great offense lately at the way infidelity is taken so lightly in the media due to the celebrity infidelity in the headlines. People truly do not realize how serious it is, and how many people are hurt by it,” commented the user bizmomof3 in response to an article written by J. D. Murrah titled Infidelity: Rebuilding Trust.
